WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 397,571, dated February 12, 1889.

Application filed November 14, 1837. Serial No. 255,116- (No model.)

To all 11 710111, it may concern:

Be it known that I, PETER \VHITE, of St. 5 Louis, Missouri, have made a new and useful Improvement in Water-Closets, of which the i following is a full, clear, and exact descripl tion.

The improvement relates more especially to that class of water-closets in which the contents of the closet-bowl are removed by siphonic action; and it consists more especially in the means employed in producing and in breaking the siphon action. Minor features of the improvement will appear in the description and be noted in the claims.

The annexed drawings illustrate the improved mechanism, and it is made part of this specification.

Figure 1 is a vertical section of the watercloset, the tank-discharge valve beingseated and the overflowpipe at its upper end being open to the outer air. Fig. 2 is a vertical section, upon an enlarged scale, of the tank, and showing its discharge-valve unseated and the overflow-pipe closed at its upper end.

The same letters of reference denote the same parts. v V

A represents the closet-bowl.

13 represents the closet-tank.

G represents the pipe for discharging the water from the tank into the bowl.

1) represents the tank discharge-valve for dtietermining the flow of the water from the tank into the dischargepipc.

E represents the air-pipe leading-from the chamber a of the bowl and connecting with the pipe 0 in such manner as to enable the downward flow of the water from the tank through the pipe 0 to cause an upward ain draft in the pipe E and thereby produce the siphon action in the bowl.

F represents the tank-lever operated by the p ull-chain G, and H represents the compound lever operated by the lever 1 all substantially as shown in water-closets heretofore made, saving as is hereinafter specially designated.

1 represents the tank overflow-pipe, its upper end, 1', coming above the normal level of the water J in the tank, and its lower end, i, connecting with the pipe 0 below the valveseat (Z. As thus far described the pipe I is similar to what has been used in connection with a water-closet tank. In the present instance, however, the construction is sup plementcd by means for closing the upper end of the pipe when it is desired to exhaust the air from the bowl-chamber a and for opening the upper end of the pipe when it is necessary to arrest the air-exhaustion. To this end, as the most desirable means therefor, the pipe I is provided with a cap, I, adapted to be closed upon the pipe or raised therefrom by attaching it to the arm F, that is pivoted at i to some supportsay a bracket, 1' upon the pipe Iand is extended beyond the pivot, as shown at The movement of the lever F serves both to unseat the valve D and to close the cap I upon the pipe I, and, as the most desirable means for transmitting the lever movement, the arm h of the lever H is extended and made, by passing it through the loop of the valve air-escape pipe d, to so connect with the valve as to lift it from its seat when the chain G is pulled, and also, by passing the lever-arm h under the end of the caparm i to turn the arm 1' upon its pivot and close the cap. This position is shown in Fig. 2. The water now flows from the tank through the pipe C, and the air is exhausted through the air pipe E upward from the bowl-chamber a, and the bowl is emptied in the usual manner. The valve I) then seats, and in seating it draws downward the end of the cap-arm, and the cap in consequence is raised from the pipe I. The outer air at once passes into the pipe I, and thence into the pipe 0, and the siphon action produced by exhausting the air upward through the air-pipe E is arrested. This last position is shown in Fig.

The air-pipe E, at its lower end, in place of connecting it directly with the bowlchamber a, may, shown substantially in Fig. 1, be connected indirectly therewith-- that is, with. a chamber, a, whose connection in turn with the main chamber (tlS at a level, a below that of the upper edge, a of the partition o in chamber a. This mode of connection is very important, in that it influences a downward How of the bowl contents from the top of the partition (0 before they pass the entrance for the air into the sub-chamber a, and thereby prevent the bowl contents from being sucked into the air-pipe E.

I desire, so far as opening the pipe I at its Ioo upper end is concerned, not to be restricted to the form of tank-valve shown, nor to the air-pipe d as a means for connecting the tank-Valve with the lever II or with the caparm nor to the particular means shown for opening and closing the upper end of the pipe I, as in all these particulars the construct-ion may be modified without departing from the principle of the improvement namely, causing the overflow-pipe to be closed as the tankvalve is unseated and to be opened as the tank-Valve is seated.

I claim- 1. The combination of the tank, the tank discharge-pipe, the tank-valve and lever operating the same, the pipe I, cap and cap-arm,

and the connection uniting said cap-arm and tank-valve to move said cap and open said pipe I to the outer air as said tank-valve is seated, the airpipe E, the closet-bowl, and the trap, substantially as described.

2. A water-closet howl having in its bowlchamber a a partition, on", combined with the air-pipe E, connecting with said chamber a by means of the chamber a at the lower end of said pipe and its outlet a below the level a" of said partition a, substantially as and for the purposes set forth.

Witness my hand.

PETER NVHITE.
